I need to parse an Encapsulated Post Script file into Java program. More specifically, I need to be able to extract simple vectors and curve elements from it, and manipulate them after this. Is there a Java library which can do this?
ToastScript looks like it may be what you are looking for.

Has anyone ever been involved with exporting JSON like this one in my sample made only for the purposes of this conversation:
https://gist.github.com/slavisah/97b57a5826dc0b49ee22895035eb244a
It represents a list of material objects (wood, metal etc.) Requirement is that every material has to be written in one line of CSV file with all of it's behaviors and properties, and their sub-lists in relation to them in the same row. Every list is N sized.
My question is how to structure that CSV file for easiest export/import in my application? Maybe someone is familiar with Java library which is capable of doing things like this?
Thanks.
Some good libraries for working with csv files using java...

i suggest you to use Apache poi the Java API for Microsoft Documents : https://poi.apache.org/
Hi I need to view code of an .exe file which has to be loaded dynamically. So, is there any method of obtaining source code of an exe file in Java or do I need another language to do that?
Standard Java will presumably not be able to do this because what you want to do is platform specific.
I don't know any library that is able to do this.
What you could do is take the exe, extract its code segments and compare their content to a list of opcodes. You could then for example simply iterrate over the bytes and create a list how often hex 0x90 is found, which is an indication for a nop.
Perhaps it is a better solution to simply disassemble the file (into "sourcecode") and count the occurences based on their text representation.
I have some pig output files and want to read them on another machine(without hadoop installation). I just want to read a tab-seperated plain text line and parse it into a java object. I am guessing we should be able to use pig.jar as dependency and be able to read it. I could not find relevant documentation. I think this class could be used? How can we provide the schema also.
I suggest you to store data in Avro serialization format. It is Pig-independent and it allows to handle complex data structures like you described (so you don't need to write your own parser). See this article for examples.
Your pig output files are just text files, right? Then you don't need any pig or hadoop jars.
Last time i worked with Pig was on amazon's EMR platform, and the output files were stashed in an s3 bucket. They were just text files and standard java can read the file in.
That class you referenced is for reading into pig from some text format.
Are you asking for a library to parse the pig data model into java objects? I.e. the text representation of tuples & bags, etc? If so then its probably easier to write it yourself. It's a VERY simple data model with only 3 -ish datatypes..
Is there any Java alternative to PHP Tokenizer?
http://php.net/manual/en/book.tokenizer.php
Edit: I mean Java class that parses Java like PHP Tokenizer parses PHP.
I quickly scanned the documentation you linked to. It looks like functionality for parsing PHP code.
If that is indeed what you are looking for, you might find the JavaParser project useful. It contains functionality for parsing Java source code.
This page contains some usage examples.
Hee,
I currently am using NSCoding to write my objects to data and save them to an file in objective-c.
Does anybody know if there is a way to use the same coding to decode the object structure in an Java application?
Thanks
Quite probably the easiest way is to use the third-party plist Java library.
Otherwise, you've got the problem that OS X supports two different types of property list — XML and binary. XML's easy enough and the relevant wikipedia page even includes a quick summary of the tags. You can use the command line tool plutil to convert any property list to XML format but the default is binary so that's not much help if you need there to be no manual step in between.
Apple don't seem to have a formal documentation of the binary format, but their code is open source so you can reverse engineer it from here.
